MRI Consortium: Acquisition of Instrumentation for High-Speed/Radiation-Hard Optical Electronics Design and Testing

该MRI联盟收购奖为俄亥俄州州立大学和南卫理公会大学的粒子物理组提供支持，以升级其电子和诊断仪器，使他们能够领导非常高速的光学数据链的开发，用于瑞士日内瓦CERN大型强子对撞机的ATLAS实验升级。 虽然仪器将对ATLAS的特定子系统（包括像素探测器的IBL（或可插入B层）和液氩（LAr）量热法）产生直接影响，但仪器将对需要超高速数据链路的各种应用具有更广泛的适用性。这项工作的智力价值与ATLAS的发现潜力直接相关，ATLAS在2012年与CMS共同发现了希格斯玻色子。在这一发现之后，ATLAS合作继续寻找其他超越标准模型物理学的证据，包括超对称性，像素探测器和LAr系统是其核心。这包括研究包含第三代夸克的末态：在像素系统中检测到衰变顶点的b夸克，以及具有轻子和喷流的顶夸克，其能量（和丢失的能量）是LAr量热系统的主要测量责任。该计划的更广泛的影响包括增强支持者的校园实验室，这将直接影响研究生和本科生的研究和培训，并有望促进与其他校园研究人员的互动，包括工程和其他科学学科。

This MRI Consortium Acquisition Award provides support for particle physics groups at Ohio State University and Southern Methodist University to upgrade their electronic and diagnostic instrumentation, to allow them to lead the development of very high-speed optical data links for the upgrade of ATLAS experiment at the CERN Large Hadron Collider, Geneva, Switzerland. While the instrumentation will have direct impact on specific subsystems of ATLAS including the IBL (or insertable B layer) of the Pixel Detector and for Liquid Argon (LAr) Calorimetry, the instrumentation have will have broader applicability to a wide variety of applications requiring ultra high-speed data links. The intellectual merit of the work is directly related to the discovery potential of ATLAS, which with CMS in 2012 co-discovered a Higgs Boson. Following that discovery, the ATLAS collaboration has continued its search for evidence of other beyond the Standard Model physics including super symmetry, for which the pixel detector and LAr systems are central. This includes the study of final states containing third-generation quarks: b-quarks with decay vertices detected in the pixel system, and top quarks, with leptons and jets, whose energy (and missing energy) is a principal measurement responsibility of the LAr Calorimetry system. The broader impacts of the program include the enhancement to campus laboratories of the proponents, which will directly impact research and training of graduate and undergraduate students, and which is expected to foster interactions with other campus researchers in including those engineering and other science disciplines.
